手扳葫芦具有安全可靠，经久耐用；性能好，维修简便；体积小，重量轻，携带方便；手板力小，效率高；结构完善，外形美观等特点。手板葫芦广泛地应用于造船、电力、运输、建筑、矿山、邮电等部门的设备安装，物品起吊、机件牵拉等。手扳葫芦分为钢丝绳手板葫芦、环链手扳葫芦。手板葫芦具有上述很多优点，用途广泛，使用时安全要求有一下几种： It is safe and reliable and durable. Good performance and easy maintenance; Small size, light weight, easy to carry; Small force, high efficiency; Perfect structure, beautiful appearance and other characteristics. The calabash is widely used in shipbuilding, power, transportation, construction, mine, post and electricity, etc. Hand lever calabash is divided into wire rope calabash, ring chain hand lever calabash. The calabash has many advantages, and is widely used. （1）使用手扳葫芦时，起重量不准超过允许荷载，要按照标记的起重量使用。 (1) when using the hand-lever calabash, the weight shall not exceed the allowable load, and shall be used according to the weight of the mark. （2）使用时不能任意的加长手柄，因手扳葫芦的起重量是有限的，两手扳力也有一定的大小，加长手柄会造成手扳葫芦的超载使用，致使部件损坏。 (2) when using can't handle any longer, because of the lever hoist lifting weight is limited, two lever force also has a certain size, longer handle can cause lever hoist overload use, damage the part. （3）要经常检查钢丝绳有无磨损和扭结、断丝、断股，凡不符合安全使用的一定要更换。 (3) check whether the wire rope is worn and twisted, broken and broken, and must be replaced for safety use. （4）由于手扳葫芦的工作原理是利用夹钳交替夹紧钢丝绳的，所以要求使用钢芯的钢丝绳而不能用麻芯钢丝绳，因麻芯绳柔软而富有弹性，在夹钳夹紧后有易松动的现象，是不安全的。 (4) due to the operation principle of the lever hoist is using alternating clamp clamping wire rope, therefore requires the use of steel core and cannot use hemp core wire rope, wire rope for hemp core wire is soft and elastic, easy to loose after clamp clamping phenomenon, it is not safe. （5）手扳葫芦使用前要作全面的检查与测验，使用后要维护保养。 (5) it should be inspected and tested in a comprehensive way before use, and maintained after use.
